Abstract

The invention provides a multistage efficient ozone air floatation integrated device. A dissolved air floatation zone and an ozone oxidation zone are arranged reasonably so that dissolved air floatation zone and ozone oxidation are vertically combined in a column and multistage oxidization is realized; solid-liquid separation of insoluble floc particles and water is completed by virtue of dissolved air floatation, and then decolorization, deodorization, organic matter removal and sterilization are realized by virtue of ozone oxidization. The multistage efficient ozone air floatation integrated device is used for performing air floatation treatment and multistage oxidization on treated water; as a result, the shortcoming of low utilization rate of ozone is overcome, the minimization of energy consumption is realized, the utilization rate of ozone is greatly increased and the effect of sewage deep treatment is effectively guaranteed.

Description

technical field [0001] The invention belongs to the technical field of advanced sewage treatment, and relates to advanced sewage treatment technology, in particular to a multi-stage high-efficiency ozone air flotation integrated device. Background technique [0002] Ozone air flotation process is an advanced treatment process for urban sewage, which has the characteristics of good color and organic matter removal, short residence time, and small footprint. However, limited by the dissolved gas technology, the highest dissolved gas rate in the traditional process is only 10%, which will result in the inability to dissolve the required dose of ozone gas under the condition of a reasonable amount of backflow water, and the undissolved gas will be discharged, resulting in waste. Moreover, the ozone mixed gas prepared from the air source contains a large amount of other air components, so that sufficient ozone gas cannot be guaranteed to participate in the reaction. At the same...
